Hi,
Does anyone have some information of the '63" on this frontmudguard ?
I did calculate C5117150 as WM20.83750 from S1048, late '42 early '43.
mudguard is brown, tip is green.
Thanks in advance, Michiel

Hi Michiel. A green surface is always an infantry battalion. In this case is number 63 AN infantry battalion belonging to an armoured division as Ron suggested. Numbers 60, 61 and 62 on green are also the Numbers of infantry batallions in AN infantry division.
You can find most Numbers and colours in the book The British Soldier, volume 2.
As you know I live near Arnhem Holland. If you PM your mobile number I can send you some pics of the pages of the book.
Do you have a picture of the whole bike?
Regards, Ramon

Michiel, as Ramon suggests there is lots of information and nice colour plates in that book by Jean Bouchery. Here is the relevant page. Ron

Good Job, Ron.
These are the pages I meant in my comment.

Thanks!, will look after that book.
I assume the markings are the Original ones, at least that is why I bought the pile of bits in France.
It was not complete and little rusty but most of the bits still had the Original paint, so saved as much paint as possible, hope you like it.
Cheers, Michiel
WM20.63546
That's a very nice find. I really like the color. Is it an M20 or KM21?

I don't think Service brown was used till 1942

Yes, most of it is khaki, I put together what was in the pile of bits, the frame and enginenumbers are matching WM20.63546, but they don't match with the frontguard - WM20.83750.
The numbers have clearly been on there for ages, so should be genuine I think. Here some close ups:
Henk also told me the censusnumbers on the frontmudguard are not commom but he did find a wartime photo of one, but not a BSA. Will look for it.
As I was mainly attracted by the numbers I very much like your opinions on it.
This cut-off piece also came with it:
This one looks to be more khaki than brown and on second thought maybe the complete mudguard is also khaki but got its brown look from the rust. 
C4865488 = WM20.81505
It all looks quite good but I don't have any photographic evidence to confirm. Certainly old oil-based paint and all applied in the correct way.
I have quite a number of photographs of Canadian Nortons around 1942/43 showing the census number on the front mudguard. I suspect that it may have been because they were so keen on putting the maple leaf on the fuel tanks.
However, Canada didn't officially take any BSAs but photos exist showing that they sometimes acquired them.
If it were mine, I might take a look at the war diary for the Argyll & Sutherland Highlanders of Canada to see if they refer to BSAs.
Here's one but unfortunately the rider seems to have lost his uniform Seems like a nice boy though

Hi Michiel
Does the rear frame have the brazed on prop stand lug or have you used a bolt on clamp type in the lower position, I can't quite see from this angle?

Must be Dutch, look at the registration plate...
Thanks for the laugh, Ron, lost its uniform 
Hi Rob, I used the brazed lug on the frame for the fieldstand.
The rearmudguard is a plain one and drilled for the pannier rack, I might put those racks on in the future but that would mean a change to the long stand.
